to preserve the original solution separated,

and also the wash solution, for subsequent treatment in order to precipitate and remove such valuable ore or material as may be contained therein.

The invention contem lates the provislon I of means whereby the solld bodies after bein separated from the original solution an washed may be discharged from the appa-- ratus.

The invention consists broadl in the provision of a plurality of receptac es and a device, preferably in the form of a filter, adapted to progressively cooperate with each receptacle and means acting through said device or collector for efiecting the performance of different 0 erations during the progressive movement 0 the collector.

The invention further contemplates the provision of devices for throwing said means into and out of operative relatlon with the collector while the same is in the act of performing its different functions With said receptacles.

The invention further consists in the provision of means for throwing the filter into and out of operative relation with said receptacles as the same is progressively brought into proximity thereto. I

The invention will be more fully described in connection with the accompanying drawings and will be more particularly pointed out and ascertained in and by the appended 5 is a sectional view taken on line 5-5 of Fig. 3. Fig. 6 is a detail plan view on a large therewith. Fig. 2 is a sectional viewscale of a portion of one of the tanks and the filter tray and its supporting frame. Fig. 7 is a sectional view on line 7-7 of Fig. 6. Fig. 8 is a detail section on line 88 of Fig. 6.

Like characters of reference designate similar parts. I

As shown:-B designates a receiving receptacle or tank adapted to initially receive the combined solids and liquids-tobe separated.

G designates a tank adapted to containa suitable wash to which the solids from the receiving tank B are subjected.

D designates a dump or delivery receptacle or tank into which the solids are deposited after the same have been subjected to the wash.

T designates a device in the form of a filter ada ted to be projected into the receivin tan to collect a portion of the solids an liquids therefrom said collector thereafter being projected into the wash tank to wash the collected solids and being finally brought into delivering proximity to the dump tank to discharge thereinto the washed solids. able devices, presently to be described, cooperate with the filter to not only bring the same into operative relation to theseveral tanks but to also enable the filter to perform its several functions while in said operative relations.

Considered more specifically with reference to the drawing the tanksB, C and D are disposed in circular order about a centrally disposed actuating mechanism and the said tanks are provided with inner and outer circular walls and are se arated from each other by radial partitions H and M. Tank B is preferably provided with a plurality of agi tators E to maintain the contents of the tank B in .a continuously agitated state keeping the solids in suspension and generally serving to facilitate the operation of collecting the solids by the collector T. Preferably the pulp or other solution of solid and liquid is fed to .the tank B through an auxiliary or feeding receptacle G located adjacent the tank B and preferably on a horizontal lane I have shown a pipe g disc arging into the receptacle G and in order to renderthe feed automatic and maintain a substantially constant level in the tank B Iprovide a float g in the tank G which may serve many of the well known ways to out off and cut in the supply through pipe g. An agitator E is provided in the tank G which serves Suitpower.

The filter T preferably consists of a tray which is provided on its under surface with a plurality of cavities preferably in the form of a series of corrugations T. A sheet of filteringfmaterial ,T is stretched across the face of the lower corrugated surface of the tray T and is rigidly anchored at its margins by a frame X between which and the edges of the tray the filtering material is clamped. A supporting frame X extends beyond the tray T and carries at its outer end a wheel T adapted to run upon a circular track Z. The track Z is provided with elevations Z, Z Z adj acent the partitions K, H and M. As the tray is progressively moved into operative relation with the several tanks B, C and D, the wheel T rides upon the track Z and the raised portions serve to raise the frame X I and lift the tray out ofthe tanks and permit the tray to pass freely over the partitions.

The said track forms or constitutes the means several tanks. the frame X by pendent links or and the said frame extends rearwardly toward the centrally disposed actuating mechanism and is secured at w, and x to a support Y preferably in the form of a pipe which extends outwardly to the tray T and communicates with the corrugations or cavities therein.

Referring to the centrally disposed actuating mechanism in detail and with reference to the accompanying drawing F designates as a whole'a vertically disposed rotatably mounted hollow shaft or spindle. At its upper end said shaft is provided with a bearing at P and is equipped with a cylinder A. The shaft is rotated as shown by means of a worm wheel D mounted on cylinder A which is driven by a Worm S. A piston C,-adapted to be actuated from any suitable source of power, operates in cylinder A to force air outwardly throughthe plurality ofoutlets B for a purpose which will be hereinafter more fully described. The said mechanism being hereinafter referred to in connection with other operative parts as an ejecting mechanism. A chamber D provided with a plurality of inlets E communicates through pipe F with an outlet G which may be connected with any desired suction means such as .an air pump,

this mechanism being hereinafter-referred to as-a solution delivery mechanism. A cham- .ber H provided with inlets K and closed to communication with chamber D by pipe F delivers to an outlet L also connected-with an air pump or other like means and this mech- -erative relation with the several tanks.

anism will hereinafter be referred to as the wash delivery mechanism. Next referring more particularly to the structural details of the parts hereinbefore described a designates an upper section provided with a flange a which is secured to flangesf and h of parts F" and H. Part H is rotatably mounted at R and is provided with an extension h delivering to a housing L which is'preferably stationary, a packing gland M serves to mairie tain a tight joint between the parts L and H above the outlet L. A gland M serves to maintain a tight joint between the housing L and the ipe F below the outlet L. The outlet G is ormed in a housing G which receives the lower end of-the pipe F and a packing gland O is provided for maintaining a tight joint between said parts.

Reference will now be made to devices whose function it is to throw the pressure ejecting, solution, and wash delivery mechanisms into and out'of operative relation with the filter during its progress from tank to tank.

The pipe Y is provided with a valve y connected by a pipe Y with cylinder A. Said valve y is preferably. of the piston type and carries at its lower end a roller y. Said pipe Y is also provided with a valve U which is I connected with "chamber H by a pipe 1'. The valve U is also of the piston type and is provided with a roller u. A third valve (1 is interposed in the pipe Y whichlatter connects 1 at its inner end with chamber D said. valve (1 also being of the piston type and being provided at its lower end with a roller d. circular support W is provided with tracks I w, wand 70 over which the rollers y and a Said tracks are provided with ralsed portions w, w and w so disposed with and d run.

respect. to the several tanks as to open-the several valves at predetermined points in the claimed and forms no part of the present invention the details of construction thereof are not herein shown,

The operation is as follows. Power is applied through worm S to rotate thecentrally disposed mechanism and therewith the filter to bring the same progressively into op- 17 will also be assumed that the piston C is operating and also the pumps for producing the vacuum through outlets L and G and that the tank B is filled to the required level with the mixture to be separated and that the tank C has been supplied with a suitable wash. The filter T in the position shown in Fig. 2 will be partially submerged in the contents of tank B and the roller (1' will be engaged by the raised portion to serving to open said Valve d and place the suction chamber D in communication with the tray T.

This operation serves to draw the solid matter of the mixture toward the filtering surface and also serves to draw the liquid therethrough into pipe Y throu' h valve (1, cham- 3 ber D and pipe F to out et G. I It will be noted that the raised portion w is of sufficient length to maintain the valve (1 open as.

long as the tray T occupies a position above the tank B. It will also be noted that the tracks w and W are fiat at this point and therefore the valves U and 1 are closed.

As the collector T rotates in a clockwise direction toward the partition K the roller T strikes the raised portion Z and the tray T Fig. 2 in the tank B. As soon asthe tray reaches the tank C the valve U will have been opened by the roller u striking the I raised portion w the other two valves-being same-into the receptacle D.

closed by reason of the absence of raised portions on the tracks w and 'w adjacent the tank C; Upon opening the valve U the wash delivery mechanism H is thrown intocommunication with pipe Y through valve U and pipe Y the latter leading to chamber H which communicates with outlet L.

The wash solution is thereupon drawn through the solid particles adhering to the filtered surface of the tray and the said solid arti-- cles are washed and any partoi the solic 'par ticles which pass off-through the wash solution may be subsequently preciptated. As

the tray approaches tank '1) the roller T .ing in combination, a pluralitv of tanks, it

strikes, a ralsed portion Z which lifts the tray out of tank C and raises it above the partition H. At this oint the raised pord or terminated and is closed. The roller (1 of the valve d strikes the raised portion '10" openin the valve (1 and also throwing the pie through valved and pipe Y. into com uni,-
